  • For mount drivers that do not protect against it, SGPro will now condition both right ascension (values greater than 24) and azimuth (values greater than 360) before sending slew commands.
  • When SGPro fails to save an image to disk, the notification will be much more specific about the nature of the error.


  • Addressing rotator docking module and handling for sky vs mechanical angles.
  • Fixed a condition in which SGPro might crash or fail initialize the Equipment Profile Manager when querying certain types of ASCOM switches.
  • Fixed a condition that might cause the older native QSI driver to cause a crash.
  • Fixed an issue where a failure to reach the MSS licensing server might reset the SGPro license to the Lite version.
  • Fixed an issue where drag to reorder targets might corrupt that targets events in certain circumstances (remote desktop especially)
  • Fixed an issue where several potential errors during the optional pre-flip wait period would not propagate that issue to the notification system.
  • Fixed an issue where SGPro might crash during evaluation of an image for Image History.
  • Fixed an issue where the camera may not disconnect at end of sequence if the camera had already been warmed up from a previous unsafe event.
